Rashad would struggle to get a takedown for the exact same reason he wss shut out entirely by Machida. The distance between the hips of a Southpaw v. Orthodox fighter is much larger than righty v. righty. Chael took Andy down with a double leg, because Chael is a lefty. Rashad will have to shoot for single legs because of yhe distance. Andys success against singles is practically 100% in the Ufc and i cant think of a single quality lefty Rashad has ever taken down.

Point: Rashads wrestling is nowhere near as "good" as Chaels for going against Anderson.
